Mineral: Almandine
Formula: Fe3Al2(SiO4)3
-Show where each of the cations in the formula are housed & describe where the M1 and M2 cations are located in this crystal system.
Homework Answers
Almandine consists of groups of independent, distorted SiO4 tetrahedrons, each of which is linked, by sharing corners, to distorted M2O6 (M2=aluminum) octahedrons, thus forming a three-dimensional framework. The interstices are occupied by M1 divalent metal ions ( M1= Fe2+), so that each one is surrounded by eight oxygen atoms that are at the corners of a distorted cube. Therefore, each oxygen is coordinated by two M1, one M2, and one silicon cation. The configuration of the array is such that Almandines are isometric (cubic).

Consider the system shown in the figure right, where two blocks m1=5 kg, and m2=10 kg are connected to each other
Consider the system shown in the figure right, where two blocks m1=5 kg, and m2=10 kg are connected to each other by a string that passes through a massless pulley. The stiffness constant of the spring attached to m1 and the wall is k=120N/m and the coefficient of kinetic friction between m1 and the surface is given to be μk=0.2. If the system is released from rest when the spring is at its equilibrium length and m2 is at a...
